CAR-TRUCK.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed December 29, 1915. Serial No. 69,183.

To all whom it may concern:

Be it known that I, FELIX KOCH, a citizen of the United States, residingat No. 62 North Harrison avenue, Bellevue, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovements in Car-Trucks, of which the following is a specification.

An object of the present invention is to provide improvements in what isknown to railway engineers as the F ox type of truck for railway rollingstock, or in trucks of similar type, and particularly to increase thestrength of the truck without increasing its size or materially changingits proportions.

Railway cars have increased in capacity from, say 60,000 lbs. in 1900 to120,000 lbs. or more, in 1915, but little attention has been given tothe strengthening of the Fox type of truck, the same having been usedpractically without change in construction notwithstanding such increasein car capacity, one of the reasons therefor being that the side framesof these trucks are formed by pressing sheet metal to shape in expendiesuseless.

Anexample of the Fox type of freight car truck is illustrated in UnitedStates Patent No. 168,146, granted to D. L. Barnes, February 2nd, 1892.An example of the Fox type of truck especially adapted for locomotivetenders is found in UnitedStates Patent No. 505,159, granted to S. Fox,September 19th, 1893, both of these patents illustrating trucks in whichthe side frames are formed of pressed steel.

Trucks of the Fox type are constructed with rigid side frames which attheircentral portions support the transoms, the side frames transmittingthe load from the transoms to the car axles through the medium of Ushaped pedestals formed at the ends of the rigid side frames, whichpedestals receive and are supported by springs mounted on the axlejournal boxes, the legs of said pedestals also forming hearings in whichthe journal boxes slide vertically. Somean example of such built-up sideframe be- 553A31, granted to C. T. Sc'hoen, January 21st, 1896.

A specific object of the present invention is to strengthen the sideframe of the FoX type of truck in such a manner as to adapt it for usein connection with railway rolling stock of the increased capacityhereinbefore referred to without changing the contour of the truck frameor materially increasing the general dimensions and proportions of thetruck.

This invention is illustrated and described in its adaptation for use asa freight car truck, but without special description it will be readilyappreciated that the improvementsare equally applicable to all trucks ofthe Fox or similar type when adapted for use in connection withlocomotive tenders. Only so much of the Fox truck will be described asis necessary to illustrate this particular invention, references beinghad to the accompanying drawings in which like characters refer to likeparts, and in which:

Figure 1 is a sectional side elevation'of a Fox truck, Fig. 2 is asectional plan view of thesame, and Figs. 3 and 1 are vertical sectionstaken on lines 3-3 and 11 respectively of Fig. 1. Figs. 5, 6 and 7 areSeetional views taken on line 55 of Fig.1, showing modifications of theconstruction of the upper portion of the side frame.

Referring now in detail to the drawings, 1 indicates the side frame ofwhat is known as the Fox type of truck, this side frame being similar incontour to the side frames illustrated in the patents hereinbeforereferred to. The plate forming the side frame 1 is bent inwardly alongportions of its upbuilt up of plates and commercial sections, 7

edge, and at its end edges in the manner shown at 5 in Fig. 4 of thedrawings, and also bent inwardly toward the longitudinal center line ofthe truck at points indicated by 6, ,6 in Figs. 1 and 2 of the drawings.When the plates 1 and 41 are placed together it will be seen that thecentral portions 7 and 8 respectively contact with each other and may besecured together by rivets or other suitable means. It will also beapparent that as the result of the bending of plates 1 and st in themanner above described, there will be a space 9 intervening between theend portions of said plates, said space being taken up and maintained inthe pedestal portion of the frame by projecting portions 10 on thepedestal members 11, which are secured. in position between the framemembers 1 and 4, by any suitable means.

The space intervening between the upper edge portions and end edgeportions is shown in Fig. t as being taken up and maintained by anauxiliary or re-inforcing member 12, which may be of angular, or anysuitable section, and in Fig. 5 as of T section.

Fig. 6 shows a modification of the last described construction in whichthe edge portions of the frame plates 1 and 4. are bent toward eachother a sufficient distance to make contact between them, thereinforcing member 13 of Z, or other suitable section is secured to saidedge portions by rivets passing through the reinforcing member and edgeportions of the frame members.

Fig. 7 illustrates a further modification in which the edge portions offrame plates 1 and 4t are spread farther apart or bent away from eachother a sufficient distance to admit of the insertion therebetween of areinforcing member 14:, of channel or other suitable section; saidmember being secured in' position by suitable means passing through theedge portions and re-inforcing member.

15 indicates the transoms or cross-tie members which serve to tietogether the frame members 1 and etforming the opposite sides of thetruck, these transom members being braced and stiffened by the usualcrossbrace members 16 and the center brace member 17.

18 indicates a gusset member adapted to assist in securing together andbracing the transom members 15, the side frame mem bers 1 and 1, and thereinforcing members, the gusset member being secured to the upper flangeof the transom member 15, and to the flange of the re-inforcing member.

Further description of the essential parts of the Fox type of truck willbe found in either of the aforementioned patents, and hence featureswhich are not pertinent to the present invention are not describedherein.

Having thus described the invention,

end edges of said plates, and a pedestal 7 member secured between thespaced end portions of said plates.

2. In a car truck, a side frame comprising a plurality of connectedplates, the ends of said plates being bent laterally of the side framein opposite directions to form a re cess, an angular member securedalong the top edges of said plates, and a pedestal member extendingbetween and secured to said plates within said recess.

3. In a car truck, a side frame comprising a plurality of connectedplates, one of said plates being offset outwardly at its ends, and theother of said plates being offset inwardly at its ends, a reinforcingmember secured along the top and end edges of said plates, and pedestalmembers secured ,between the offset portions of said ends.

4. In a car truck, a side frame comprising a plurality of connectedplates extending the full length of said truck, a pedestal membersecured to said plates, said plates being offset laterally of the sideframeto form a recess for the reception of said pedestal member, and areinforcing member secured to the top edges of said plates.

6. In a car truck, a side frame comprising a plurality of platesextending the full length of said truck, portions of the ends of saidplates being spaced apart, pedestals extending between and secured tosaid end portions, and a reinforcing member secured to the top and endedges of said plates.

7. In a car truck, a side frame composed of two plates, portions of saidplates being secured together in contact with each other, the otherportions being spaced apart, and an angular re-inforcing member insertedbetween and secured to said spaced apart portions, said member extendingfor the full length of said plates.

' 8. In a car truck, a side frame composed of two plates, portions ofsaid plates being secured together in contact with each other, the otherportions being spaced apart, a flanged re-inforcing member securedbetween said spaced apart portions, and a gusset plate secured to theflange-of said reinforcing member.

9. In a car truck, side frames, each composed of two plates, portions ofsaid plates being secured together in contact with each other, the otherportions being spaced apart,

a re-inforcing member secured between said spaced apart portions,transoms connecting the side frames, and gusset members connecting saidre-inforcing members and transoms.

10. In a car truck, a side frame comprising a plurality of platesextending the full length of said truck and having pedestal openings intheir ends, said plates being oifset around said openings, and pedestalmembers extending between and secured to said offset portions.

11. In a car truck, a side frame composed wholly of two plates, the endportions of said plates being ofi'set laterally of the truck in oppositedirections, and pedestals extending between and secured to the offsetportions of said plates.

12. In a car truck, a side frame comprising a plurality of connectedplates extending the full length of said truck, the end portions of saidplates being offset laterally of the truck in opposite directions,pedestals secured between the end portions of said plates, and areinforcing member secured along the top and end edges of said plates.
